AM2 SECTION A

AM2 Section A: AM2 Section A — Composite Installation — 8 hours 30 minutes — the longest section

Section A is the AM2 composite installation — 8 hours 30 minutes of cable selection, containment, circuit installation, terminations and final connections, all to the drawing and BS 7671. The longest single section by far, and the one most candidates lose marks on through poor first-hour planning.

Key Takeaways

  • 1Section A is 8 hours 30 minutes — the longest section by far. About 50% of total AM2 time.
  • 2Marked on workmanship, drawing compliance, BS 7671 compliance and time management. Rushed work loses marks even when electrically safe.
  • 3Cable size must match the drawing exactly. Using 2.5mm² where the spec calls for 4mm² is non-compliance regardless of whether the install passes testing.
  • 4Containment — trunking, conduit, tray — must be installed straight, level, with neat bends. Conduit edges must be deburred or you lose workmanship marks.
  • 5ELV and mains conductors must be segregated where the spec requires it. Mixing them is a fail for spec non-compliance + safety breach.
  • 6The 8h 30min splits roughly: ~2 hours marking out + containment, ~2 hours cable pulling + dressing, ~2.5 hours terminations + connections, ~2 hours testing + documentation.

What Section A actually covers

Section A is the composite installation. You install a complete electrical installation from drawings — typically including a sub-main, distribution board, multiple final circuits (lighting, power, motor, special-location), containment (conduit, trunking, tray), terminations and accessories. Section A1 covers the risk assessment and initial setup. Section A2-A5 covers the actual installation work. The assessor is watching the whole time — your method, your decisions, your workmanship — not just the finished product.

02 · AM2 Section A

Time breakdown within Section A (8.5 hours total)

  • Phase 1 — Marking Out + Containment (~2 hours): set out cable routes, mark accessory positions, install trunking, conduit and tray to drawing.
  • Phase 2 — Cable Pulling + Dressing (~2 hours): pull cables through containment, dress neatly, label at both ends, allow service loops.
  • Phase 3 — Terminations + Connections (~2.5 hours): make off cable ends, terminate at accessories and distribution board, label every conductor.
  • Phase 4 — Testing + Documentation (~2 hours): dead tests, live tests, complete the EIC schedule, hand over to the assessor.

What assessors mark you on

  • Drawing compliance — cable size, circuit count, accessory positions all to spec.
  • BS 7671 compliance — protective devices, RCD selection, segregation, special-location rules.
  • Workmanship — trunking lids flush, conduit deburred, bend radii correct, terminations tight.
  • Cable management — neat dressing, glanded SWA, supported runs, no kinked bends.
  • Documentation — every circuit labelled, schedule of inspections complete, EIC schedule populated.
  • Time management — finished on schedule with all sections of the install complete.

Common mistakes that lose marks

  • Cutting conduit and not deburring — sharp edges damage cable insulation and fail workmanship.
  • Pulling cables too tight, not allowing service loops at accessories.
  • Trunking lid not flush or installed crooked — visible on the assessor walkaround.
  • SWA glands fitted incorrectly — armouring not properly terminated, lack of earth continuity.
  • Wrong cable size against the drawing — fail for non-compliance regardless of testing result.
  • Time over-run on the first phase, leaving inadequate time for terminations + testing.
  • Missing segregation between ELV and mains where the spec required it.

One App for Everything!

Elec-Mate is my go to app for business and electrical work. It's feature rich without feeling cluttered. A true all in one app for quotes, certs, calculations, RAMS, EICRs, and more. I use it every day without fail, and it makes my workflow much smoother since I'm not jumping between apps anymore. The price-to-feature ratio is excellent. Any issues I've had, the developer responds within the hour and usually fixes them the same day. 100% recommend.
